Sure, as will changes due to editing the actual files or buffers.  Of
course, editing occur/grep buffers necessitates toggling the read-only
flag so its presence/absence can be taken as an indicator for the
preciousness of such a buffer.  And of course, you can always
rename-uniquely to save a buffer.

My point, namely that an easibly accessible history regenerated
transparently is much cheaper than buffers to keep around.
